| To meet the increasing need for bioenergy several raw materials have to be considered for the production of e.g. bioethanol and biogas.In this study, three lignocellulosic raw materials were studied, i.e. (1) winter rye straw (Secale cereale L), (2) oilseed rape straw (Brassica napus L.) and (3) faba bean straw (Viciafaba L.). Their composition with regard to cellulose, hemicellulose, lignin, extractives and ash was evaluated, as well as their potential as raw materials for ethanol and biogas production. The materials were pretreated by wet oxidation using parameters previously found to be optimal for pretreatment of corn stover (195 1C, 15 min, 2 g l_1 Na2CO3 and 12 bar oxygen). It was shown that pretreatment was necessary for ethanol production from all... |

| It is very much debated whether bioethanol is a sustainable energy resource that can offer environmental and long-term economic advantages over fossil fuels, like gasoline or die-sel. From the present first generation bioethanol technology focusing on starch (from grain) fermentation GHG savings are only modest. The Danish Integrated Biomass Utili-sation System (IBUS) has developed both first generation and second generation princi-pal bioethanol technologies characterised by integration with an existing coal-fired Com-bined Heat and Power (CBH) plant. To secure that bioenergy is produced from local adapted raw materials with limited use of non-renewable fossil fuels there is a need for integrating the biomass starting point into the energy manufacturing... |
